Summary

Acknowledgement of the existence of instant axis of speeds and accelerations and necessity of the annulment of notion about instant axis of rotation is based in spherical motion of a body.

Possibility of statement spherical motion kinematics of a body is showed on the base spherical trigonometry.

Summary

It has been proved that welding heat-resisting steel structures using electrodes containing heat-producing mixtures (Al-Cr₂O₃) gives noticeably higher factors of recovery of alloying elements by the weld. The research was held on the basis of selecting a welded structure heat treatment mode that would reduce probability of cold cracks in the zone adjacent to the weld. This article describes the results of the research as to the effect the tempering mode may have on the temper of the zone adjacent to the weld and on the weld microstructure.
